JEWEL-SETTING. TOOL.

To all whom it may concern:

Be it knownthat I, CARL. CULMAN, a citizen of the United States, and residing at Maplewood, county of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Jewel-Setting Tools, of which the following is a specification.

This invention relates to a combination tool used by watch repairers.

One of the objects of this invention is to provide a tool which can be used for setting the jewels in a pallet, and which is so constructed thatone jewel may beset without interfering with the setting of the other.

.Another object "is to provide a tool adapted .tobe used to set the jewel with respect-to a roller-table of a balance, and more -especially,.one which will. set the jewel with respect to a doubleroller table. -.'Further:objects are to provide a tool of the type described'which can be used for variousixother operations in the repairingof a watch or a clock.

Furtherobjects will appear from the detail description taken in connection with the accompanying drawing, in which:

This toolis an improvement on the tool illustrated in United States Patent 'No. 817,955, April 17 1906. As in the tool illustratedinithe patent, it comprises a handle 1, the forward end of which is bifurcated to form a-ringlike spring structure 2 and arms or jaws 3, thesejaws being extended laterally. to" form thermally separated heating platesiorxwingsg.4, adapted to be impinged bya flame as hereinafter described. In this tool, however, the arms 3 are extended forwardly, asshown at 5, to form tapering .end jaws. The. jaws 1 are. connected by a screw 6 threaded into one jaw, and having a looseswivelsbearingwin theother jaw, the swivel bearing being formed by an annular groove-.7: in..the.screw,-and the jaw being 'peened.in,masshown at 8,1 to form lugs taking into the grooves to form the swivel connection. With:.this construction, the jaws can-be spread apart-or broughttogether by adj ustment offthe; screw- 6, w

spring steel-,the end 10 of which. is slotted, as shown at 11, to receive the shank of a set screw 12, which is threaded into thehandle, a concave spring washer 13, of usual construction,-being interposed between the screw head and the end of the clamp, so as to frictionally clamp the same in position on the handle. A set screw '14 is threaded into the clamp intermediate of its ends, and bears on the body or handle of the tool. The forward endof the clamp is bent downwardly, as shown at 15, and'forwardly, as shown at 16, to form a bifurcated endcorresponding with the bifurcated jaws of the tool body. Itwillbe particularly noted "that under this construction the bifurcated part of the clamp straddles the spacebetweenthe separated jaws 3, and presents independent portions adapted to coact'respectively with said jaws in clamping a watch element therein. Now inasmuch as the jaws" 3 are thermally separated, in order that one of said jaws may be heated without transmitting this heat to the other jaw, it is apparent that through the medium of the clamp having separated portions'adapted, respectively, to the separate jaws, provision is made for clamping onto either of the jaws, an element to be heated by the heat applied to that particular jaw Without incurring the risk of this heat being transmitted through the'clamps to the otherv jaw or an element which may be held thereon. This is of marked importance in the efficient operation of "the device, for the reason that the integrity of the thermal separation of the jaws is thus positively insured. It will be understood that the end "10 of the clamp extends flush with the tool handle for some distance on each side of the pivot, whereby a bearing is formed which will tend to hold the bifurcated end of the clamp-downon the" aws. iThe jaws'are raised either-by hand. or by the adjustment of the screw 14. With this construction, furthermore, the 'clamp'canbe swung upon its pivot 12 laterally with respect to said" base or can, through the slot or screw connection 11-12 moved longitudinally so as to position the ends 16 of the clamp inany desired relation. with-respect to the jaws.

"Thej'aws 3 are provided withplates- 17 similar in constructionand operation as 'in the patent referred'to, these plates being pivoted on'thearms by screws 18- andhaving beveled ends 19 and pointed ends 20, adapted to cooperate with graduations 21 on the arms. A pallet 22, of any suitable construction, is thus adapted to be supported onthe jaws 3 with the pallet jewels 23 inengagement with the faces 19, the pallet being clamped to the jaws by means of the bifurcated end 16 of the clamp, the bearing or staff 24 of the pallet passing between the jaws 3 and the end 16 of the clamp. With this construction, permitting its longitudinal movement, the pallet can be positioned as desired.

The jaws are grooved longitudinally, as shown at 25, so that any suitable article, such as a balance staff 26, Fig. 2, 01' a roller table 27, Fig. 4, may be held between the jaws. Furthermore, the pointed ends of the jaws adapt this device to be used as an ordinary pair of forceps. The jaws are apertured or recessed, as shown at 28, to receive a roller table 29, in order to position the roller table with respect to a jewel or ruby pin 30 clamped between the jaws. In the double roller table, 'the latter is provided with an upper flange 31, to which the jewel is attached, and a lower flange 32, in which is the crescent. Now, with this construction, in which the jaws are grooved, and in which the apertures or recesses 28 extend into the grooves, the roller table can be positioned so that the lower flange 32 extends into the groove, thereby enabling the jewel or ruby pin 30 to be positioned close to the flange 32, at the same time allowing suflicient material between the recesses and the edge of the jaw to give ample strength. The jaws may further be provided with nicks or grooves 33, so that the jewels or stafls may be readily held in position.- The roller table is held in place, during the application of the ruby pin, by means of the clamp, and the adjustable connection of this clamp enables the jaw to be placed directly over the roller table.

It will thus be seen that a tool is provided. which is adapted to be used for a variety of purposes and operations. At the same time, it is simple in construction as well as operation, and is, therefore, cheap to manufacture. The operations of applying and adjusting the jewels to and with respect to a pallet and roller table, are well known, and a detail description of these operations is, therefore, unnecessary. Suflice it to say that the jewels are usually attached by shellac, which is softened by heating. In this case, the heating is accomplished by applying aflame tothe extended plates 4, and owing to'these plates being thermally separated, through themed'ium of the spaced jaws 3 and bifurcated structure 2, heat may be applied to either of said plates without being transmitted to the other or to the handle '1, It is obvious that various changes may be made in the'details ofconstruction without departing from the spirit of this invention, and it is, therefore, to be understood that this invention is not tobe limited to the specific construction shown and described.

Having thus described the invention, what is claimed is: v

A jewel setting tool comprising a base constructed and arranged to provide a pair of distinct, thermally separated jaws adapted to support a watch element, a clamp opere ative for holding the watch element on said base, said clamp being common to both of said jaws, andmeans sustaining said clamp for lateral movement with respect to the said base, adapting said clamp to be shifted to positions for proper coaction with either of said j aws to clamp thewatch element.
